MZ21 Seires Disk Positive Temperature Coefficient Thermistor 19P
18mm 100R 120C 600V For Welding Machine
Working Principle
15P (100R) 16P (5R) 19P (100R) MZ126A (12R)
Connect the PTC thermistor in series in the load circuit. When the
circuit is in normal working condition, the current through the PTC
thermistor is less than the rated current. The PTC thermistor is in
the normal state and the resistance is small, which will not affect
the normality of the protected circuit. jobs. When the circuit
fails, the current greatly exceeds the rated current (2 times of
the normal working current), and the PTC thermistor suddenly heats
up, showing a high resistance state, so that the circuit is in a
relatively "off" state for protection purposes. When the fault is
removed, the PTC thermistor automatically returns to a low
impedance state and the circuit resumes normal operation.
Application

The main production line and inspection equipment & instrument are imported from Japan, America, Belgium and Switzerland and Taiwan etc. The annual production capacity of the two leading products has been reached to 5 million pcs and 150 million pcs respectively, with the market holding rate in China of about 10% and 30% respectively by continually technical innovation. Varistors and SPD produced by the company enjoyed great reputation in the international market, being exported to many countries and areas such as Japan, USA, Hong Kong etc., with the customers like Philips India and GE in USA. FBT are already sold to LG company in Korea with large quantity, and also to Spain and India etc.
